wow, since before she could talk - it's incredible - there are some physical health concerns as mentioned above @kaliju - i would tend to agree with you though in the sense of technology, smart phones in particular open up our kids world. And like any new invention it has pros/cons. The use of it really depends on the training attached to it.
I have a problem when its used as a babysitter, and parents neglect their role - specifically in social settings. I think the social IQ has the potential to be the biggest challenge.
We will see..
